Alstroemeria plant named ‘Jamoa’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Jamoa’, characterized by its erect and strong flowering stems; vigorous growth habit; large purple and white-colored flowers with purple-colored flecks and streaks, flowers arranged in symmetrical umbels; and excellent postproduction longevity.

Botanical designation: Alstormeria hybrida.

Cultivar denomination: ‘JAMOA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a cut flower Alstroemeria, and hereinafter referred to by the name ‘Jamoa’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventors in Madrid, Cundinamarca, Colombia. The objective of the breeding program was to create new Alstroemeria cultivars with desirable plant qualities, attractive flower color and excellent postproduction longevity.

The new Alstroemeria plant originated from a cross-pollination conducted by the Inventors in Madrid, Cundinamarca, Colombia in February, 2004 of a proprietary selection of Alstroemeria hybrida identified as code number PJA 858, not patented, as the female, or seed, parent with a proprietary selection of Alstroemeria hybrida identified as code number HH 325, as the male, or seed, parent. The new Alstroemeria plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Madrid, Cundinamarca, Colombia in April, 2005.

Asexual reproduction of the new Alstroemeria plant by rhizome divisions in a controlled greenhouse environment in Madrid, Cundinamarca, Colombia since June, 2005, has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possible environmental and cultural conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Jamoa’. These characteristics in combination distinguish ‘Jamoa’ as a new and distinct cultivar of Alstroemeria plant:

-   -   1. Erect and strong flowering stems.     -   2. Vigorous growth habit.     -   3. Large purple and white-colored flowers with purple-colored         flecks and streaks, flowers arranged in symmetrical umbels.     -   4. Excellent postproduction longevity.

Plants of the new Alstroemeria can be compared to plants of the parent selections. Plants of the new Alstroemeria differ from plants of the parent selections primarily in flower color as plants of the female parent selection have pink-colored flowers and plants of the male parent selection have red purple-colored flowers. In addition, perianth segments of plants of the new Alstroemeria are more deeply emarginate than perianth segments of plants of the male parent selection.

Plants of the new Alstroemeria can be compared to plants of Alstroemeria hybrida ‘Tescupi’, not patented. In side-by-side comparisons plants of the new Alstroemeria differed primarily from plants of ‘Tescupi’ in the following characteristics:

-   -   1. Plants of the new Alstroemeria had slightly smaller umbels         than plants of ‘Tescupi’.     -   2. Plants of the new Alstroemeria had more flowers per         inflorescence than plants of ‘Tescupi’.     -   3. Plants of the new Alstroemeria had smaller and more rounded         flowers than plants of ‘Tescupi’.     -   4. Plants of the new Alstroemeria and ‘Tescupi’ differed in         flower color.     -   5. Perianth segments of plants of the new Alstroemeria were more         deeply emarginate than perianth segments of plants of ‘Tescupi’.     -   6. Plants of the new Alstroemeria and ‘Tescupi’ differed in         anther and pollen color.     -   7. Plants of the new Alstroemeria and ‘Tescupi’ differed in         ovary color.     -   8. Plants of the new Alstroemeria had shorter pedicels than         plants of ‘Tescupi’.
